Claims.

This invention relates to improvements in nozzle holders, and more particularly to a device especially adapted to firmly, but quickly removably hold and support a fire hose nozzle on the running board or other suitable surface of a re apparatus vehicle.

A primary object of the present invention ls to provide a nozzle holder, mounted on a portion of a fire apparatus vehicle, which will permit the easy mounting thereon and quick removal therefrom of a re hose nozzle, the holder clampingly engaging the nozzle in a manner to prevent the nozzle from being dislodged or removed through jolting of the moving vehicle, while permitting easy and quick manual removal of the nozzle without the manipulation of any auxiliary levers, clamps or other devices.

A further object of the invention is to provide a nozzle holder which does not have a threaded engagement with a nozzle mounted thereon and consequently the nozzle threads can not become bruised or injured.

A further object of the invention is to provide an expansile and contractile nozzle holder devoid of external manipulating or clamping devices which might be exposed to and rendered ineffective by ice and dirt.

A further object of the invention is to provide a vehicle carried re hose nozzle holder which is relatively small and compact and may be mounted on an out-of-the-way portion of the vehicle, which is strong and durable and inexpensive to manufacture, which is positive in its engagement with a nozzle and which is easily and quickly operated under all conditions, and which is well adapted for the purposes set forth.

With the above and other objects in view the invention consists of the improved nozzle holder, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: y

Fig. 1 is a perspective view of a fragment of a re apparatus vehicle running board showing the improved holder mounted thereon and rmly supporting a detached fire hose nozzle;

VFig. 2 is a perspective view similar to Fig. l only with the nozzle removed from the holder;

Fig. 3 is a transverse sectional view taken on line 3 3 of Fig. 2 and on a slightly larger scale;

Fig. 4 is an enlarged, fragmentary, detail sectional view through the base portion of the holder and the vehicle running board, the nozzle being removed; and

Fig. 5 is an enlarged, fragmentary, detail sectional view through the upper portion of the holder with the same expanded and the nozzle removed.

Relatively large nozzles are threadably carried effected. A convenient place on a by the discharge ends of re hoses. Due to the fact that when a re hose is not in use it is carried on a re apparatus vehicle in coiled condition itis the practice for a fire apparatus to carry a re hose nozzle detached from its hose. In fighting a re, time is of the essence and consequently when the apparatus arrives at its destination the nozzle must be quickly and readily accessible and removable from its mounting on the truck, the mounting for the nozzle must be unaffected by exposure, ice and dirt, and the internal threads of the nozzle must be maintained undamaged and unmarred so that quick attachment of the nozzle to a hose may be vehicle for the mounting and transportation of a re hose nozzle is the running board and in the present invention the improved nozzle holder is preferably, but not necessarily, so located. However, this subjects the holder and nozzle to severe jolting and also `to the likelihood of ice formations thereon during winter. The present improvement takes into account all of the aforementioned contingencies and effectively guards against disadvantages flowing therefrom, as will appear from the following description of a preferred embodiment of the invention.

The nozzle holder per se comprises a pair of complementary independent half sections 8 and 9 of T-form in transverse section to provide laterally projecting webs I0 and inner faces II with the outward extents of the inner faces forming webs angularly separated from the webs 8 and 9. Each half section 8 orl 9 has a at semicircular shouldered base portion I2 and when mounted is positioned substantially vertically and is relatively elongated, being reduced or tapered toward its upper extremity. The upper end oi' each half section 8 or 9 is rounded as at I3. In mounted cooperative relationship the face portions II of the complementary half sections 8 and 9 are adjacent one another.

Y The complementary sections 8 and S of a nozzle holder are preferably mounted on a convenient portion of a running board I4 of a fire apparatus vehicle in the manner best shown in Fig. ll. The attaching means for a section 8 or 9 comprises a pair of elongated bolts -I5 disposed on opposite sides of the central webs I0 and extended through apertures therefor in the base portions I2. The running board I4 is provided with vertical openings I6 in substantial registration with the bolts I5 and through which the bolts depend, there being retaining nuts I1 on the lower threaded end portions of the bolts I 5. It should be observed that the running board openings I6 are of somewhat greater diameter than the bolts I5 to allow for play and rocking movements of the bolts therein.

There is interposed between the base portions pad I9 and through the corrugated running board f covering strip I8.

While the complementary sections 8 and 9 of a nozzle holder are mounted by the bolts I so as to normally cause the complementary inner faces I I to be in relative adjacency, the outer end portions of said sections 8 and 9 are constantly urged away from one another by means of a rather heavy short coiled spring 20 whose opposite end portions are seated and secured in recesses 2| within the upper portions of the sections 8 and 9 respectively.

A rire hose nozzle, as shown in Fig. 1, isY designated generally by the numeral 22. A nozzle of this type is formed of metal and is relatively heavy. The nozzle is also of hollow or bored formation and is tapered toward its upper or outer end.

In use, when it is desired to mount a nozzle 22 on the improved holder, the enlarged end of the nozzle is slipped over the rounded upper end portions I3 of the sections 8 and 9 and the nozzle is then slid downwardly on the holder. During the process of engagingV the nozzlel with the upper end of the holder the spring 2!)Y will be compressed so as to bring the upper end portions of the sections 8 and 9 together. When the nozzle is fully mounted on the holder the spring 20 will urge the sections- 8 and 9- apart so as to cause-the free edges or the webs of the holder sections to impinge against and firmly engage inner wall portions of the nozzle. It will thus be seen that the clamping engagement of the holder with the interior of the nozzle is eiected quickly and automatically by the mere process of inserting the nozzle over the holder. Obviously, the quick removal of a nozzle from a holder is effected in a manner reverse to that described. A simple quick upward movement of the nozzle is effective to slipthe same free of the holder sections. During the upward movement of the-nozzle the upper end of the holder will become contracted with compression of the spring 20 and a drawing together of the sections. The clamping and releasing action of the holder is not in any Way dependent upon exterior levers or other devices which could become frozen or rendered inoperative from deposits thereon. During running of the vehicle on which the holder nozzle is mounted, theV impingement of the sectionsV 8 and 9 with the exterior of the nozzle is so rm and secure as to prevent rattling of the nozzle and further to prevent jarring and jolting such as might dislodge the nozzle from the holder.

The resilient pad I9 between the base portion of the holder sections and the running board plays an important part in the eiective operation of the holder, in conjunction with the attachment of the bolts I5 in a manner to permit slight rocking movements thereof. When the sections 8 and 9 expand or move outwardly relative to each other under the influence of the spring 20 they will rock somewhat on the resilient pad I9, which permits this rocking movement and furthermore the bolts I5, in the larger hole I6, mayY likewise accommodatingly rock.

While the holder has been illustrated as composed of two complementary sections 8 and 9, it is obvious that the same may, without departing from the spirit of the invention, be composed of any suitable number of complementary mating and spring urged sections. Likewise any suitable resilient material may be used as between the base portions of the sections and the running board, and in lieu of having the running board' openings enlarged, as at I6, the openings in the base portions I2, through which the bolts pass, might be enlarged.

From the foregoing description it will be seen that the improved iire hose nozzle holder is of simple and novel construction Iand is well adapted for the purposes described.

What is claimed as the invention is:

1. A nozzle holder, comprising a support, an elongated, split nozzle insert extending away from said support and having a base portion and an outer end portion, means rockingly mounting the base portion of said insert on said support, and yielding means interposed between split outer end portions of said insert to normally urge the same apart.

2. A nozzle holder, comprising a horizontal support, an elongated, split nozzle insert extending vertically from said support and having an enlarged base portion, the body of said insert being upwardly tapered, means rockingly mounting the base portion on said support, and a coiled spring interposed between split upper portions of said insert to normally urge the same apart.

3. A nozzle holder, comprising a rigid support, an elongated nozzle insert extending away from said support and having a base portion and an outer end portion, the entire insert including said base portion being longitudinally split, means slightly rockingly mounting the split sections of said insert on said support in adjacency, a resilient member interposed between the insert base portions and the support, and yielding means interposed between split outer end portions of said insert to normally urge the same apa-rt.

4. A nozzle holder, comprising a rigid, horizontal support, an elongated nozzle insert extending vertically from said support and having an enlarged base portion, the body of the insert being upwardly reduced and the entire insert including said base portion being centrally, longitudinally split, means depending from said base portion slightly rockingly mounting the split sections of said insert on said support in adjacency, a resilient pad interposed between the insert base portions and the support, and a coiled spring interposed between split upper portions of said insert to normally urge the same apart.

5. A holder for a re hose nozzle, comprising nozzle bore entering companion sections outwardly taperedV and having laterally projecting webs for impingement with inner surface portions of a tubular nozzle slid thereover, and yielding means for holding said sections in spreading relationship against inner surfaces of the nozzle, the nozzle being quickly removable from the holder by moving it longitudinally thereon along said webs and past the tapered end and causing contraction of the sections relative to each other.
